A 28-year-old man who has had paralysis for more than ten years due to a spinal cord injury has been able to “feel” physical sensations through a prosthetic hand directly connected to his brain, and even identify which mechanical finger is being gently touched. The advance was made possible by neural technologies developed under the U.S.’s Defense Advanced Research Projects Agency’s (DARPA’s) Revolutionizing Prosthetics (RP) program.
